Some time ago, an acquaintance of mine wanted to know what the most popular free online logic puzzle games were. I decided to find out.

Armed with Opera 10 and the latest version of Flash, I went to Kongregate, one of the most popular flash game communities. The following games were those of the highest rating in the puzzle category (at the time of writing). In descending order, here they are.

Red shapes are miserable, it’s up to you to release them from their suffering. Kill them, that is. Green shapes, on the other hand, are lovely, try not to hurt them. Finally, blue shapes are neutral. You can do whatever you want to them. Easy, right?

You need to remove all red shapes from the screen without losing the green ones. Things get a tad harder when the game introduces moving objects and different shades of gravity.

This game certainly won’t exactly make the biggest intellectual challenge, but it’s easy to imagine why it’s currently at the top of Kongregate. It serves a lite snack of braintainment and manages to keep the fun up. With cute sound effects, solving a free online logic puzzle like this brings even more of a smile on your face.

Super Stacker 2, the second most popular game is pretty similar to Red Remover, which is why we won’t go too deep on it. The game uses the same cute physics style, but instead of removing items, you need to keep all of them in the level. Mad stacking skills are rudimentary.

Little Wheel heads an entirely different direction. Wonderful artwork and great animation makes this point and click adventure one of the most compelling I’ve ever seen. And an adventure it certainly is, with the developer’s only pointer being “use the mouse”. Add a grain of dry humor to the mix, and you’ve got yourself a killer.

After playing for a while, my first impressions were confirmed. This game is a cult-hit-like flashgame – original and incredibly entertaining. The level of quality is enormous, which earns the developer my well-meant kudos. If you like a puzzle adventure, and something different to what you’re used to, this game comes highly recommended.

Lately, there have been a few games like Fantastic Contraption, better described as physics puzzle engineering. Nevertheless, Fantastic Contraption is one of the best in its genre. Because of the sheer simplicity of the interface, a lot of room is left for the levels’ difficulty.

One of the mistakes I made, being overconfident with ‘puzzle experience’, was to hop in somewhere near the end of the game, only to be stuck after a few seconds. Don’t skip a level — during the game’s progress, new ‘techniques’ will be revealed that you’ll need later on.

All in all, Fantastic Contraption is an incredibly fun game. Although graphically challenged, some of the levels are not to be taken lightly. Fantastic Contraption is the most difficult of these three games, but perhaps also the most fun if you’re up for a little engineering.

I love Little Wheel because it looks so good. Too bad it's not a real big game. But it shows how good games can look.
Fantastic Contraption is a game I will not recommend to my friends, because I know they will stay up all night to play. I do anyway. I'm addicted. This is really a great great engineering game. My brains love this game.
